This could be due to a blockage in the pipe work, best option is to take pipe work of and give it a thorough clean or get in contact, we would be happy to help you on this

Hi there,
This is a very common issue. Your kitchen sink and washing machine share the same main waste drainage pipe.
Because a washing machine pumps out a high volume of water very quickly, any partial or full blockage further down the combined pipework creates a bottleneck.
Since the water cannot drain away fast enough, it takes the path of least resistance and backs up directly into your kitchen sink.
The best solution is to use a mechanical drain snake to thoroughly clear out the grease, lint, and debris built up deep inside the internal pipework, rather than just cleaning the surface U-bend trap.
